Solved the problem with a crutch, I don’t understand how to do it right. Need count the number of characters in a string.

Question

#Example:
#H12 - Harry Potter
# if I use //num = len(line)// I have H12. Why?

file = open("/usercode/files/books.txt", "r")

massive = (file.readlines())
for line in massive :
if len(line) == 18:
num = len(line)
else: num = len(line) -1
name = (line[0])
result = name + str(num)
print(result)
file.close()

Answer 1

Alexandr Grebyonkin ,

to remove the trailing newline sequence we can not code just for this constellation of the file content. see the comments:

file = open("/usercode/files/books.txt", "r")

massive = file.readlines()
for line in massive:
#if len(line) == 18: # this is coded to solve the task exactly for this constellation of file content. don't do this.
#num = len(line)
#else: num = len(line) -1
#name = (line[0])
result = line[0] + str(len(line.strip())) # add .strip() here, this removes leading and trailing whitespaces, also the newline sequences
print(result)
file.close()

Lothar your advice helped me, thanks.
It turns out that the transition to another line is also a symbol
